Hello, I gzipped a file on Android (BusyBox v1.21.1-jb bionic (version: 2013-07-25 21:23 +0100) multi-call binary) and am able to unzip it on Android. But when I copy the file on to OSX (using adb) , I am not able to decompress it. $ gzip -d -S .0 atrace_z.0 gzip: atrace_z.0: unexpected end of file gzip: atrace_z.0: uncompress failed $ gzip -V Apple gzip 251 I can still decompress on Android if I copy the file back from OSX to Android phone. Please find the file attached. Best regards, abhilash
